The Coventry-class frigates were 28-gun sixth rate frigates of the Royal Navy, principally in service during the Seven Years' War and the American Revolutionary War. They were designed in 1756 by Britain's Surveyor of the Navy, Sir Thomas Slade, and were largely modeled on HMS Tartar, which was regarded as an exemplar among small frigates due to its speed and maneuverability. The 1750s were a period of considerable experimentation in ship design, and Slade authorized individual builders to make "such alterations withinboard as may be judged necessary" in final construction.
The Bellona-class ships of the line were a class of five 74-gun third rates, whose design for the Royal Navy by Sir Thomas Slade was approved on 31 January 1758. Three ships were ordered on 28 December 1757, with names being assigned on 1 February 1758. Two further ships to this design were ordered on 13 December 1758, at the same time as two ships of a revised design – the Arrogant class.
The Dublin-class ships of the line were a class of seven 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Sandwich class ships of the line were a class of three 90-gun second rates, designed for the Royal Navy by Sir Thomas Slade.
The Valiant-class ships of the line were a class of two 74-gun third rates of the Royal Navy.
The Ramillies-class ships of the line were a class of nine 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Albion-class ships of the line were a class of five 74-gun third rates, designed for the Royal Navy by Sir Thomas Slade.
The Edgar-class ships of the line were a class of three 60-gun fourth rates, designed for the Royal Navy by Sir Thomas Slade.
The Royal Oak-class ships of the line were a class of six 74-gun third rates, designed for the Royal Navy by Sir John Williams. The Alfred class were an enlarged version of the Royal Oak class.
The Alfred-class ships of the line were a class of four 74-gun third rates for the Royal Navy by Sir John Williams. They were an enlarged version of the Royal Oak class.
The Ganges-class ships of the line were a class of six 74-gun third rates, designed for the Royal Navy by Sir Edward Hunt.
The Intrepid-class ships of the line were a class of fifteen 64-gun third rates, designed for the Royal Navy by Sir John Williams. His design, approved on 18 December 1765, was slightly smaller than Sir Thomas Slade's contemporary Worcester-class design of the same year, against which it was evaluated competitively. Following the prototype, four more ships were ordered in 1767–69, and a further ten between 1771 and 1779.
The Inflexible-class ships of the line were a class of four 64-gun third rates, designed for the Royal Navy by Sir Thomas Slade. The lines of this class were based heavily on Slade's earlier 74-gun Albion-class.
The Fame-class ships of the line were a class of four 74-gun third rates, designed for the Royal Navy by Sir John Henslow. After the name-ship of the class was ordered in October 1799, the design was slightly altered before the next three ships were ordered in February 1800. A second batch of five ships was ordered in 1805 to a slightly further modified version of the original draught.
The Nelson-class ships of the line were a class of three 120-gun first rates, designed for the Royal Navy as a joint effort between the two Surveyors of the Navy at the time, Robert Seppings and Joseph Tucker.
The Southampton-class frigates were 32-gun sailing frigates of the fifth rate produced for the Royal Navy. They were designed in 1756 by Sir Thomas Slade, and were the first 'true' fifth-rate frigates produced to the new single-deck concept. They were, however, designed with sweep ports along the lower deck.
The Niger-class frigates were 32-gun sailing frigates of the fifth rate produced for the Royal Navy. They were designed in 1757 by Sir Thomas Slade, and were an improvement on his 1756 design for the 32-gun Southampton-class frigates.
HMS Harwich was a 50-gun fourth rate ship of the line of the Royal Navy, built to the dimensions laid down in the 1741 proposals of the 1719 Establishment at Harwich, and launched on 22 December 1743.
HMS Burford was a 70-gun third rate ship of the line of the Royal Navy, built at Chatham Dockyard to the draught specified by the 1745 Establishment as amended in 1754, and launched in 1757.
The Burford class were three 68-gun third-rate ships of the line designed for the Royal Navy by Sir Joseph Allin. The Burford ships were almost the last "70-gun" ships designed by Allin. They were built to the draught specified by the 1745 Establishment as amended in 1754.
